Some clients working with Microsoft Dynamics AX might have an environment with multiple AOS’s. For example AX-AOS1, AX-AOS2, AX-AOS3, AX-AOS4, AX-AOS5 are all in an AX system cluster called “Load Balanced AOS Instances.”
You need to log into a specific AOS to perform a task. For example, you need to setup a password for an application and the password encryption includes AOS related data. You’ll have to log-in to the five different AOS’s to setup the password, so when users connect to any one of the five AOS, the application will recognize the password as a valid password.
To force an AX client to log-in to a specific AOS, you need to use the “-loadbalance=0” configuration command in the AX client config like below. Then in the Connection tab, enter the specific AOS server name/instance you want to connect to.
Save the above configuration and you will now be able to login to AX connected to that specific AOS.
